Comprehensive Knowledge of Thin Section Bearings
1. What Are Thin‑Section Bearings? Thin‑section bearings are radial ball bearings whose cross‑section (width) is significantly smaller than that of conventional bearings with the same bore diameter. They are also called thin‑walled, extra‑thin, or constant‑section bearings. Their compact profile makes them ideal for applications...
